Help with mystery wire identification

[Zeus51]

Does anyone know the wire in the pic? It is located on the drivers side headlight harness. I have located all blackout light, headlight, running light, turn signal wiring…. I think. Any help would be appreciated. I am currently running down a turn signal issue. And yes, i have tried to look at the tm’s and search this forum. Thanks for the help!

Hey. That wire goes to the brake prportional valve on the crossmember below the fan shroud. Connector is at the edge of the frame where the transmission lines cross.

Dude, you‘re awesome. Thanks for the help!

I saw a lot of squarebodies my last time through AL just before Christmas.

We love these things in AL. They’re everywhere. People even daily drive them. I’m in the middle of a restore of a m1009. Mostly done. Just got the reassembly to do. But the turn signals and brake light wiring is giving me fits. But I’ll figure it out.

Yeah, I have read through the diagrams. Honestly, I am wondering if it is a flasher relay issue or a fuse box issue but I have cleaned the grounds, cleaned the bulb contacts all the way around. And no matter what I do I always come up with these combinations:

Blackouts off and right BO switch flipped up: I turn on the lights by pulling the switch and get high and low beam but the blinkers don't work at all. BUT.... If I turn off the lights and try the blinkers they stay on constant. and sometimes it is a low dull on and not bright. Never do i get a blinking turn signal. I have replaced the hazard flasher with the 552 relay in the fuse box but I can't find the 224 one to put in the bottom right of the box. So I was trying a second 552 relay. Thoughts?

1. Do the side marker lights work? They are an integral part of the turn signal system.
2. Do the turn signal lights on the instrument panel turn on in either direction?

Also, unplug the turn signal switch under the column and clean those connectors real well also.

Cleaning the turn signal switch will be next on my list. The side markers are what are constant on when I use the blinker with lights off. And I haven’t actually connected the cluster yet but I’ll try that after I give the switch a cleaning. Any other ”to do’s“ are appreciated!

The cluster may be the issue. The lights on the cluster are the troubleshooting indicator of the system. When the left (right) turn indicator on the cluster stays on solid there is a bulb out on the left (right) side.

Then that’ll be done right after I clean the switch. I was waiting to put the cluster in when I could take the time to really clean up the whole cluster panel.

In the Army, for test purposes, we would sometimes “dry hang” a cable to verify a fault in a circuit. You might try just plugging it in for a test.

I’m embarrassed to even say that I didn’t even think about not having cluster hooked up would be causing an issue. I assumed the flasher relay would still trigger.

Lol. Bulbs should complete the circuit.

Ok. So I couldnt wait. i put brand new bulbs in the gauge cluster for the blinkers. Plugged it In. The side markers don’t blink if the lights are off. But when I turn the lights on, both blinker turn solid green on the cluster and the side markers turn to constant on.

Please double check that the hazard button is pulled out on the side of the steering column.

Copy that. And it is Pulled out. I wish we could upload videos to the forums

Ok. For my edification, key on, engine running, service light switch in the up position, headlight switch pushed in. Turn signals and brake lights should be functional.

headlight switch pulled out to first position, all marker lights, turn signals and brakes lights should be functional.

headlight switch pulled out to second position, headlights, all marker lights, turns signals, and brake lights should function

Yes. That is how the lighting should work.
